The spindle is advanced by moving the lever
(36) (See Fig. 6a). The lever is fitted with a release
pawl (39) which, when pressed, renders it inde-
pendent of the hub and hence the spindle; the
operator can therefore easily vary the angular
position of the lever without movement of the
spindle (Fig. 6b).

6b - With the release pawl (39) pressed, the lever is released
from its hub and can repeat the previous travel without
the spindle moving.
5.1) Adjustment of the advance lever
The movement of the lever must never be loose.
For adjustment proceed to tighten it by loading the
cup springs by means of the associated self-locking
nut, after removing the protective cap (see Fig. 7).
